qtwayland: Mitigate crash when platforminputcontext library is missing
Turns out that in the case a plug-in library is missing (which is the actual
root cause of this problem) we do not properly check if it can
use it, leading to a crash when attempting to make of use QT_LOGGING_RULES.
This patch mitigates that and allows to debug Qt w/ the help of
QT_LOGGING_RULES.
