This is not only style change, but also a bugfix.
Header and title font was unspecified, so terminal monospace font was
used in most cases. However, when new split with different orientation
was created, the font of splitted terminal changed to the system font.
Steps to reproduce:
* Split vertically - both titles use monospace font
* Split horizontally - splitted header's font changes to system default
Summary:
The idea is that a SplitterHeaderBar will be added in the
near future so the checks for the parent widget could be
wrong.
If instead of checking for a specific widget we check for
anything and walk to the parent list untill we find
a TerminalWidget seems sane, and safer.
Phabricator messed with this review and send the wrong diff together (because of the same parent)
so I'm rephrasing it.
