Snaps E2E Test Upgrades for the new test-snaps UI

[bowensanders]

Changes need to be made in order to make existing e2e tests work with the new test-snaps UI (see MetaMask/test-snaps#40)
This fixes both navigating through the pages as well as changes necessary to the refactor of class & id tags.

These test are now working with, and can be co-deployed with MetaMask/test-snaps#40

However it cannot be merged until MetaMask/test-snaps#40 is merged because it refactors classes to id's

Also, MetaMask/test-snaps#40 breaks the current e2e's so they have to hit at the same time 😅
