The `page_type_list` method for the message component was deprecated
in 5b0769db as part of MDL-54744. However it is still required when
trying to configure blocks on any messaging pages.

Also import missing 'core/notification' dependency.

Instead of displaying the source code, as text, display a content
indicator which tells the user what sort of content the message might
contain.

message will be shown explaining why you can not block the user.

and unread messages in the overview.

Passing the last message (which can virtually contain any character) as
a parameter for the {{#str}} mustache helper can break the JSON parsing
which eventually leads to the breakage of the messaging UI.
So for simplicity, revert the addition of the 'conversationlastmessage'
language string and render the sender and the last message as separate
elements.

Create a conversation instead of throwing an exception to get the
behaviour working as it was before.
The string lang 'conversationdoesntexist' can be removed because
it was added in MDL-63466 and it's not used anywhere more.
