Subject: [PATCH] fix(commands/build): don't start blockchain node when
 `--contracts` is used

Prior to this commit `$ embark build --contracts` spinned up a blockchain node
which is not necessary as `--contracts` can be seen as a "compile only" option.

This commit ensures we don't start any web3 services with `--contracts` is used.
