Patch: stream cache returns original stream if it cannot allocate space in cache for the new stream

[José Dapena Paz <jdapena igalia com>]

	Hi,

	This patch makes the stream cache work as it's expected in this case:
if we have a too big stream, and this doesn't fit in the stream cache,
then we return the original stream so that it's properly provided to
user.

Changelog entry:
	* libtinymail/tny-fs-stream-cache.c
	(tny_fs_stream_cache_get_stream): return original stream
	if we cannot put the stream in cache.
