Profile is added to tree even when quick pick is dismissed

[traeok]

Describe the bug

When selecting a profile to add to a tree view, users are shown a follow-up prompt that asks if it should be added to all trees or just the selected one. However, if the quick pick is dismissed, it still adds the profile to the tree.

To Reproduce

1. In one of the tree views, click the "+" button to add a profile
2. Select a profile from the list
3. When the follow-up prompt appears asking if it should be added to all trees, dismiss the prompt
4. Notice that the profile was added anyway

Expected behavior

No profiles should be added if the quick pick is dismissed.

Screenshots

Desktop (please complete the following information):

• OS: Windows 10
• Zowe Explorer Version: 2.15.4

Additional context

This might have been intended behavior when the feature was implemented, but it doesn't seem like an appropriate UX here. If we intend to fall back to this behavior when a user dismisses the quick pick, we should make it more obvious so that users are not confused when a profile is added after dismissing the prompt.
