[analysis api] fix ArrayIndexOutOfBoundsException on KtDiagnostic creation

Browse Source 
The problem was caused by concurrent access to the non-thread safe List.
This list is not needed anymore, previously it was used to store strong
references to FIR diagnostics corresponding references in KtDiagnostics
were weak references.

^KTIJ-21449 fixed
