Before this change annotation entries starting with '@' within expressions hadn't been resolved
Note that order of annotation entries in result may change according to order of children in PSI (see changed testData)
Basically, this commit splits test data from the from java-txt-kt to two pairs java-txt and kt-txt.
This commit leads to some duplication in test data.
This is temporary: in the platform types branch the test data for LoadJava tests will be changed dramatically, so duplication will go away
