Adds support for use with java-test-fixtures, a core Gradle plugin.

[Kennelly57]

Before this PR

Currently, there is no support for using java-test-fixtures, a core Gradle plugin. When using a test fixture, this plugin will fail. As an example, here is an error message that will be logged:

Couldn't determine scope for dependency: com.h2database:h2:2.2.224

if the build.gradle file is as follows:

dependencies {
    testFixturesApi 'com.h2database:h2'
}

==COMMIT_MSG==

A case to check for test sourceSets starting with the word "test" has been added, as suggested in #691 by @carterkozak. I have also included a test case to check that the lock file is properly generated when using the testFixtures plugin.

Possible downsides?

The logic is dead-simple, so it is unlikely to cause unforeseen bugs. However, this now means that the plugin may change some sourceSets from production to test. I imagine that this impact will be small because it is unlikely many people are labelling their production source sets with test as a prefix. If the impact is deemed too high, then I also would be happy just to scan for the prefix 'testFixture'

What do the change types mean?

• feature: A new feature of the service.
• improvement: An incremental improvement in the functionality or operation of the service.
• fix: Remedies the incorrect behaviour of a component of the service in a backwards-compatible way.
• break: Has the potential to break consumers of this service's API, inclusive of both Palantir services
  and external consumers of the service's API (e.g. customer-written software or integrations).
• deprecation: Advertises the intention to remove service functionality without any change to the
  operation of the service itself.
• manualTask: Requires the possibility of manual intervention (running a script, eyeballing configuration,
  performing database surgery, ...) at the time of upgrade for it to succeed.
• migration: A fully automatic upgrade migration task with no engineer input required.

Note: only one type should be chosen.

How are new versions calculated?

• ❗The break and manual task changelog types will result in a major release!
• 🐛 The fix changelog type will result in a minor release in most cases, and a patch release version for patch branches. This behaviour is configurable in autorelease.
• ✨ All others will result in a minor version release.
