Since there is no prefix/suffix it inserts first completion candidate which is taken from the scoped settings (which provide a list for Objective-C wherein retain is included).

Esc-completion changed to allow empty prefix (since it also looks at suffix now).

I can make it a no-op when both prefix and suffix is empty to help users who accidentally press keys and expect nothing to happen — the argument seems a bit weird though ;) but given that the result from pressing ESC is likely unpredictable, I won’t claim it is a useful feature to always get a completion candidate inserted, although it could perhaps be if say, a custom completion command is setup say, for my unit test files or at root level in @implementation … @end to insert boilerplate for the only unit that makes sense given the context (i.e. method for the latter, unit test body for the former).
