Revert "Postpone long-running operations to the activation of the "Tr…
Browse files Browse the repository at this point in the history 
…acing" tab."

This reverts commit 7c1f0ed from eclipse-pde#674.
The change introduced a regression causing Tracing tabs not to be
initialized properly in specific situation. It requires an update to the
Eclipse platform, which will not be integrated into the upcoming
release anymore. Therefore, the change is reverted for the release to be
reapplied after the next release.

The effect of reverting the change will be a loss of the performance
improvement in the launch configurations dialog that was gained by the
change.
