Describe the bug
Completing a symbol name does not add it in the import show clause. Therefore, becoming very hard to use explicit imports with a show clause all the time.

Steps to reproduce the behavior:

1. Write part of an existing class name and press the key to complete the class name
   

2. Press Enter to confirm and check it's not imported
   

Expected behavior
The symbol should be imported and highlighted correctly.
