testsuite: Fix gesture test inconsistencies due to legacy event handling

Legacy GtkWidget vmethods are now handled on an event controller, which
due to being the very first controller added to every widget, runs in
a different order than the previously hardcoded.

Probably testing legacy events is not really futurible, specially after
we stop installing this legacy controller by default. I'll leave the
choice to remove these specific tests for later though.
