Fix inspector not using the appropriate REPL connection

[ak-coram]

I believe 9dc5107 introduced an issue where the inspector is potentially not using the correct nrepl connection for evaluation. This is because cider-nrepl-send-sync-request defaults to (cider-current-repl 'any 'ensure) when given no connection, while calling cider-current-repl without arguments infers the correct type from the current buffer. This PR simply adds back the calls to cider-current-repl to the inspector.

Hmm, perhaps it's the default that should be adjusted, as I find the difference in the behavior a bit weird.

[ak-coram]

I guess any really means any kind of REPL, although this behaviour doesn't sound that useful.

Let me know what you prefer, but the inspector was definitely broken for me and tried sending forms from a .clj file to the CLJS connection without this change.

@bbatsov So you want me to change this PR into changing the defaults of cider-nrepl-send-sync-request or leave it as is?

[bbatsov]

I think changing the default would be better, as it's reasonable to expect it'd be using cider-current-repl.

@bbatsov are we good?
