Internally: Upgraded to AssertJ 13.2.2.

Support for hasSizeLessThan(), hasSizeLessThanOrEqualTo(), hasSizeGreaterThanOrEqualTo(), and hasSizeGreaterThan() for AssertThatSizeInspection (with AssertJ >=13.2.0).
Really fixed highlighting for JUnit conversion. Sorry.
Fixed testing code to work against IDEA 2019.1.
