[Evolution-hackers] [CamelStore] clarifying of documentation becomes a minor change of code

[Paul Bolle <pebolle tiscali nl>]

I wanted to clarify the documentation for camel_store_free_folder_info()
a bit. In found myself altering its implementation. Rationale is
(obviously) to simply make sure that camel_store_free_folder_info()
handles a NULL return of camel_store_get_folder_info() gracefully so my
documentation change is actually always correct. Any comments on this
(entirely untested) change before spamming b.g.o.?
