Fix regressions in auto-sizing of text fields for the review request page.
Review Request #1177 — Created April 26, 2018 and updated
The text fields (Description and Testing Done) on the review request page are meant to grow as you add content and shrink as you remove it. This regressed in 3.0 with the field rework due to the "resize" event not making it up to the field. `RB.TextEditorView` was emitting the event, but `RB.InlineEditorView` wasn't passing it up, and neither was `RB.ReviewRequestFields.TextFieldView`. Chaining these events up to `TextFieldView` ensures that layout calculation will take place as content is added to or removed from the text field, restoring the ability to auto-size the field. Testing Done: Manually tested that this fixed issues with auto-resizing the text fields on RBCommons. Unit tests pass. Reviewed at https://reviews.reviewboard.org/r/9853/
