[BUGFIX] Initialize tooltips only once

Due to several modules initializing tooltips, it might happen that they
are initializing the same element twice or even more times. This can be
easily avoided by using the new bootstrap Tooltip method
"getOrCreateInstance". This should fix weird behaviour, where the
tooltip did not disappear.

Also, since updating to a newer bootstrap version the fix 0005bc5 did
not work anymore. This is fixed by using the container context as
selector basis.
