Unreliability in DrillTest

Fix command to rebase branch from master to release

This commit should correct the unreliability observed in DrillTest. The
problem came from triggering a signal on the wrong object from the
InstrumentSelector widget (most likely due to a race condition during
objects replacement when runing the tests suite).

Because InstrumentSelector widget is observing ConfigService, this
commit moves the config modification instructions after instanciating
the InstrumentSelector signals listeners.

In the Curves tab, when a new curve is selected in the list widget
all tabs were enabled. Now the errorbar tab is only enabled if the data
relating to that curve has errors.
