Patch: reason folder while checking its size

[José Dapena Paz <jdapena igalia com>]

	Hi,

	This is a very small patch that avoids accessing a local folder to get
its size after it's freed. It simply adds a reason to it.

	The patch does not contain Changelog entry. It would be something like
this:
* libtinymail-camel/tny-camel-folder.c:
	* Reason the camel folder while we're getting its size and count,
avoiding some crashes.
