CommonTab: add utility to get LaunchConfig attributes without Exception

This avoids try-catch blocks when getting an attribute and increases
readability of the methods that contains logic.

In the method updateConfigFromFavorites now the update continues with
the default-value instead of stopping inbetween, if getAttribute throws
a CoreException.
