Remove deprecated properties reload the editor

Reproduction steps:

• Create an xclass with 2 string properties "Foo" and "Bar"
• Create an xobject for that xclass
• Edit the xclass to remove "Foo"
• Edit the xobject in the object editor
• Edit the property "Bar"
• Click on the link to remove deprecated properties

Expected result:

• the deprecated properties link should run in background, preserving the changes performed in the editor

Obtained result:

• a confirmation dialog is opened asking if the user wants to leave the editor, if the user refuses a notification appears saying that deprecated properties are removed, but in reality it's not the case
• if the modified property was done in a select, then the editor is reloaded without confirmation dialog leading to loosing change (because of XWIKI-24319)
