When we double click a link/button, a link dialog appears
to update the target properties, and since the current link dialog
can only handle anchor targets, using it on buttons leads to some
inconsistencies :
- visible href options for button & url required to save changes.
- missing preview when button style changed.
...
The goal of this commit is to add a fix (with minimum of code) on
summernote linkdialog to handle button elements using the same logic as
anchor nodes.
Also, update website form test tour to test those new changes.
