[BUG]: Missing tests from Alpha MR5

[seanlip]

Some PRs that were merged for the MR5 release (in Aug 2022) have additional tests that need to be written. These are described below:

• Fix #4495, part of #3088, #4467, #4505, #4266, #4446: Miscellaneous alpha MR5 fixes #4506
  • Tests for single-line/multi-line hint text for interactions: text input, math expression input, ratio input, fraction input, numeric input
  • Test for new default hint text for text input interaction
  • Tests for new audio notice that shows when the current playing language can't continue for voiceovers (presence show/hide + specific languages)
  • Tests for ExplorationProgressController passing the correct answer object for event logging
  • Tests for LearnerAnalyticsLogger correctly converting all supported answer types to stringified versions
  • Tests for EventBundleCreator correctly including stringified answers even for non-sensitive situations, and that they're capped to 100 characters
  • Test for ProfileManagementController that profile name validation is disabled when the learner study feature is enabled
• Fix #4494: Hint bulb animation added #4501
  • Tests for the new LifecycleSafeTimerFactory changes (and maybe refactor away createTimer in favor of the new methods)

The aim of this issue is to write these tests.

(This issue was originally part of #4510 but has been split out to isolate the "missing tests" action items.)
