1.4.0 fixes

[raphaelcoeffic]

This is an attempt at fixing 2 issues seen with 1.4.0:

• "BF script page changed when switch between telemetry page and script":
  • NEXT_PAGE / PREV_PAGE events are now only evaluated when the script is not executed as a telemetry script.
• "values changed back after editing":
  • this is probably caused by the fixed page reading timeout (800ms) generating multiple requests.
  • when the first reply has arrived, the user starts editing the page.
  • when the next reply arrives, the changes are wiped.
  • the fix invalidates subsequent replies.

@0crap sorry about that, it's fixed now.

The issue with the PAGE button is solved. Tested on my Taranis QX7S.
The other issue in this PR, I can't comment on that one because I have not seen that specific problem.

Thx!

Thanks for doing this so quickly, I just experienced the bf page flipping bug and was making a video to post.

Update: worked for me to fix the bug :)
