[READY] Not using --release on CI when building racerd

[Valloric]

We don't use the --release flag on Travis/AppVeyor because it makes building racerd 2.5x slower and we don't care about the speed of the produced racerd.

The 2.5x slower number is from my local workstation, but I'm guessing it's similar on Travis as well.

In development mode, the racerd executable is not built in the same folder (target/debug instead of target/release). Tests are passing on Travis Linux because of the cache. What we could do is move the racerd executable to the right folder.

Heh, I arrogantly thought "no need to test this out locally, it's such a trivial change I can just send it out." Serves me right.

Fixed now.
