#2648 enabled pause debugging action

Previously it was enabled by default, changed in JetBrains/intellij-community@e9a81e6

Intended behavior is - the button is always enabled to promote the feature, but if user presses it when action not available, he gets a notification with an explanation.

Fixes #2648
