Extend tests for bindable properties

QTestPrivate namespace has a set of helper functions to test bindable
properties.
Use them to test the bindable properties of QWebChannel, as they could
potentially have issues with binding loops.
The updated tests didn't reveal any issues, so no further action is
required.

Fixes: QTBUG-116544
Pick-to: 6.6 6.5
Change-Id: I2f826fe0d286b8370edba34bd6d8e3553512a387
