Opening OPI that have scripts is slow #2644

We have an issue with freezing OPI windows with CSS version 4.6. The problem is somehow connected with using scripts. Whenever we add scripts to a few controls in OPI window and then try to open the window with OPI Display, CSS freezes for a significant amount of time. We were using empty scripts to be sure that script content is not the cause for the delay. If we use CSS version 4.5.9, OPI window opens without significant delay.

CSS 4.6 was tested with Java 11, CSS 4.5.9 with Java 8.

It seems it's a duplicate of #1197 We added -Dpython.import.site=false to the VM arguments and now it works fast again.
