Subject: Convert the cache key from unicode to a string.

The memcached API expects string format, not unicode.
Convert the key passed to the memory cache to a string
before sending it to memcached. Since both the function
name and the id that form the key are ascii format, a
simple conversion from unicode to str is sufficient.

Change-Id: I9d15858ad4e10aa183444cccda9c33676059e55a
Fixes: bug #1174487
