BF: When compiling code for JS the html/js templates didn't honour useVersion

As a result in 2021.2.0 - 2021.2.1 the JS experiments would fail to run
if comiled with a different useVersion due to the change in import format
in 2021.2

Problem arose in Commit 9cda6f5 because this led to psychopy.experiment
being imported before the useVersion had been set
