KT-37144 Respect quotes in package name during decompilation

- Odd package names (for example `try` in `arrow-core`) were pasted
as-is to the decompiled text
- Because of this, stub checks were failing, forcing completion to start
over and over again, as if something changed in the files
- See EA-5572315 for the error
- ^KT-37144 Fixed
