Explain the impact now: new contributors think about tests,
and encourage tests to be written without being overbearing
And future plans: moving to a codebase with better coverage and
better formalizing the requirements for writing a test for GSoC
This PR has changes besides the output of the java-kotlin IDE migration tool:
- the tool made the fields in FieldControllerBase as nullable which triggered a lot of changes in
subclasses for adding !!. To reduce the number of changes this PR tackles the nullability of the class properties and
made them lateinit var
- there's one extra getter method added for the mActivity field because one of the subclasses' test requires access to
the field. It is possible to access protected fields from the same packages in java but this isn't possible in kotlin
code.

it doesn't have a options menu to invalidate, so it isn't necessary
Overriding `onBackPressed()` is necessary because it triggered the default `finish()`, and finish() shouldn't be directly overriden because AnkiActivity deprecates it
Overriding `onActionBarBackPressed()` is necessary because super's (AnkiActivity) equivalent finishes without animation
Reviewer is the only inheritor of AbstractFlashcardViewer which calls `openCardInfo`
Another reason is to simplify the use/importing of the constants/methods necessary to implement the reverse transitions on finish
