tst_qmediaplayerbackend: Guard unchecked MaybeUrl dereferences

Several test functions dereferenced the MaybeUrl results without cecking
if it is valid. This causes us to hit q23::expected's 'has_value()'
asserts, which makes this test crash instead of skipping.

QML, Screen/WindowCapture: Shadow 'maximumFrameRateChanged' signal

Currently, both the QML and C++ variants of this signal is exposed to
QML. One is exposed under the name 'maximumFrameRateChanged', the other
is exposed under the name 'qmlMaximumFrameRateChanged'. We can instead
shadow the C++ variant since it cannot be correctly used from QML
anyways.

This patch instead provides us with a single 'maximumFrameRateChanged'
signal on the QML side, with the correct parameter list for QML.

Additionally, we add some QML auto tests to make sure this signal
works as intended.
