poping up Activity dahslet raises a javascript error in french

When you have the activity dashlet on your dashboard. You open a popup when you click on the zoom icon.
At this moment, with the french translation, an error is raised.

This is due to a not generalized way of handling localization.
In the file templates/CRM/Activity/Selector/Selector.tpl, we find :
"""
ZeroRecordText +=

' for Activity Type = "'

"""
Two errors occured in this string :

• First the position of the ' which is inside the translated string.
• Second, there is no escape="js" provided.

A quick solution is given in the attached patch.

Important note : the two elements 'First' and 'Second' described here above are the source of plenty of bugs when you are using localization (for example the one with the Dashboard configuration).
