Patch: small fix to avoid a lock joining the imap idle thread

[José Dapena Paz <jdapena igalia com>]

	Hi,

	Following the patches for removing threads on closing tinymail, this is
a fix for them.

	This should avoid trying to join the thread inside the thread loop
(happened when disconnect was called inside it).

Changelog would be:
* libtinymail-camel/camel-lite/camel/providers/imap/camel-imap-folder.c:
	* Avoid joining idle_thread from itself causing a crash/lock.
