This change will hopefully help some tests that occasionally fail
on TC. After setting the options during the test setup we sync the
settings before running the test scenario.
This also fixes a failing test (`048 - modifier keys keep context`)
if surrounding text is not supported. If the user presses the
capslock key we shouldn't reset the context if no rules match.
Fixes#5613.
Previously we overwrote our test data, so we basically ran the same
test repeatedly under different names.
Properly running them showed some failures which this change also
fixes or skips.
This change adds integration/regression tests for ibus-keyman. It
re-uses the unit tests that we have for core.
Also modifies one test so that the context doesn't use characters
used in the keyboard. This makes it easier to setup in ibus-keyman
tests.
