Update generic_select

Changes:
- Moved some functions for options below checks for the correctness of passed options
- Removed unnecessary `continue` from `except ...`, since the loop will return to the beginning anyway
- Added stripping of `selected_option` straight on input
- Changed check `len() == 0` to `not ...`
- Returned changing string to number on check
===
- Removed '!' as they look weird inside such ` * ... * ` log style (Change for generic_multi_select)
