fix #54501: Tied enharmonics incorrectly notated

[Fyrult]

Only if the previous tied note has the same accidental, then the current note's accidental should not be shown.
Edit: a word

[MarcSabatella]

I'm not understanding how this addresses the issue. With your change, how does the user create a note tied to its enharmonic equivalent?

[Fyrult]

*This fixes the previous behaviour where the accidental was always not shown if there was a tie.
In other words, if one "J"s the tied note, the accidental (if there is one) is shown since the enharmonic equivalents would have different accidentals.
