Fix T81161: Bad properties context panel placement loading old files

These breadcrumbs used to be a panel in 2.79 and 2.80 development.
If a file was saved in those versions, and the panels rearranged in a
version that didn't have this panel, its sortorder would be changed
even though it wasn't visible or even used in that version.

A simple fix is to use a new ID name for the new version of this
panel in 2.91. "Buttons" is an old name anyway.
