If a name is passed to EVP_<OBJ>_fetch of the form:
name1:name2:name3
The names are parsed on the separator ':' and added to the store, but
during the lookup in inner_evp_generic_fetch, the subsequent search of
the store uses the full name1:name2:name3 string, which fails lookup,
and causes subsequent assertion failures in evp_method_id.
instead catch the failure in inner_evp_generic_fetch and return an error
code if the name_id against a colon separated list of names fails. This
provides a graceful error return path without asserts, and leaves room
for a future feature in which such formatted names can be parsed and
searched for iteratively
Add a simple test to verify that providing a colon separated name
results in an error indicating an invalid lookup.
