evas: Prevent crashes in case of error

SEGV would happen if the cache was NULL, as the error pointer
was also NULL in some cases (root cause for cache == NULL not
quite known, happens in elm_suite with CK_FORK=no).

Note: simply adding evas_common_init() to evas_init() leads to
a whole new set of issues with CK_FORK=no elm_suite - not good.
