RFR: 8289647: AssertionError during annotation processing of record related tests

Wed Jul 20 14:05:30 UTC 2022

This PR fixes a situation where the same record component was entered *and* schedule for later annotation at the same time.

The test case of the original bug report was recreated as part of "RecordCompilationTests". I tested that it breaks with the expected assertion error mentioned on the original bug report, without the proposed changes.
