Bug#884372: openshot-qt hangs at start: No module named 'PyQt5.QtWebKitWidgets'

[Jordan Christiansen <xordspar0@gmail.com>]

I have a workaround for this. I noticed that I had PyQt5 installed in my 
~/.local/lib directory. This version had most of the PyQt5 submodules, 
but not QtWebKit or QtWebKitWidgets. When I removed my local libraries with

pip3 uninstall PyQt5

then openshot searched for all the PyQt5 modules in the system 
directories and was able to find QtWebKit.
