BUG: 515379 - fixed infinity loop when degree token is found in calculation

Fix a bug causing an infinite loop when degree token is found in calculation, which causes the app to freeze completely. In this case, degree token has type set to KNumberType (maybe a default type for tokens) so kcalc_core tries to insert next token after it and it fails. As a simple solution, Degree token is completely removed from the parser because it is not used at all in the program

BUG: 515379

Closes #515379
