Problems with 'hide system barline'

Issue type

Engraving bug

Bug description

The behaviour of 'Hide system barline' (in Stave/Part properties) is problematic: turning it on then off does not update the score; and visually it's inconsistent above and below the stave where it applies.

Steps to reproduce

First issue:

1. Create a score with at least 2 instruments
2. Turn on 'Hide system barline' for one; click OK
3. Turn it on again, and note that the score does not update to reflect the change. It'll only be fixed after a save/close/reload.

Second:

1. Create a score with 3 instruments
2. Turn on 'Hide system barline' for the middle one
3. Note that it behaves differently above and below:
   

We could argue about whether the above or below behaviour is preferable here; I feel like it would be better for the barline not to extent beyond the stave either side of that for which it has been hidden - i.e. as though 'Span to next stave' were turned off (for the system barline only).

This problem can also be seen in a 2-stave set up (the behaviour is different depending on which stave you hide the barline on), it's just more obvious with 3+.
