LiveData inline editing fails when entry reference contains ':'

Prerequisites:

• Create a custom class
• Create entries and rename on of them to include : in the reference (e.g. My\:Entry)

Steps to reproduce:

• Insert a livedata

{{liveData id="LiveData-Table" properties="doc.title, _actions" showPageSizeDropdown="true" source="liveTable" sourceParameters="className=MyCustomClass"}}{{/liveData}}

• Save changes
• Trigger editing action on entry of table
• Try to save it

Actual result

LiveData will return an error: “The row save action failed” without saved changes.

Expected result

No errors and changes are saved.

Note that originally this issue was mixing up what's described above and what's described in XWIKI-23604
