Fix failure of the cli "--export" command on Windows.
Fixed the random failure of the command "krita test.kra --export --export-filename test.png" on Windows OS caused by try_lock() failing on the document image file.
The genesis of the fix can be found here: https://krita-artists.org/t/krita-api-commandline-interface/23128
It is a simple timing based fix (QThread::msleep(2);). A logic based fix might be more desirable.
Test Plan
Execute the command "krita test.kra --export --export-filename test.png". Previously this failed about 9 of 10 times on windows. Now it suceeds.
