Renaming a class when the message browser is open breaks

[Ducasse]

handleClassRenamed: anAnnouncement
| items selectedIndex |
items := self messages
collect: [ :rgMethod |
| interestedClassName interestedClass |
interestedClassName := anAnnouncement oldName.
interestedClass := anAnnouncement classRenamed.
rgMethod isMetaSide
^^^^^^^^^^^^^^^^^^^^^^^^^
ifTrue: [ interestedClassName := interestedClassName , ' class'.
interestedClass := interestedClass classSide ].
rgMethod parentName = interestedClassName
ifTrue: [ (interestedClass >> rgMethod selector) asFullRingDefinition ]
ifFalse: [ rgMethod ] ].
selectedIndex := messageList selectedIndex.
self messages: items.
self setSelectedIndex: selectedIndex

[Ducasse]

This is because a ring method does not have the same api than a compile method and that isMetaSide is only defined on RG.

Solution should probably be

• check compiledMethod and Ring Method
• check what is the status of Ring
• make sure that both are compatible

Confirmed in release Pharo8.0-SNAPSHOT-64bit-278304f.
No idea in which state it lets the code.
