Wrong warnings raised as checkNoUnusedImports

[phdmakk]

On module NR_Timing, imports on lines 11;12;13 and 14 are needed but the tool raises the checkNoUnusedImports message.

import from NR_CellInfo all;
import from NR_Component_Base all;
import from Common4G5G_Timing all;
import from Common4G5G_Templates all;

You could see the same warning on some other modules, for example:

..\ENDC\7_1_2\RLC_ENDC_NR.ttcn: 18: WARNING: Code Style: No definitions from imported module "NR_Timing" are ever used! (6.18, checkNoUnusedImports)

Indeed, there was an issue with parsing "select union ...". The observed problem was an indirect consequence of that. The issue has been fixed.
