Use adjustWidths for TrueType fonts if we handle them as OpenType (issue 5027, issue 5084, issue 6556, bug 1204903)

Browse source 
In `Font_checkAndRepair` we can decide that a font isn't TrueType, and instead parse it as CFF. In that case it's quite possible that the `fontMatrix` will be changed, and without calling `adjustWidths` we're failing to update the glyph widths correctly.

Fixes 5027.
Fixes 5084.
Fixes 6556.
