Plugin template references non-existent branc

The generated plugin project fails to compile.

===> Verifying dependencies...
===> Fetching emqx (from {git,"https://github.com/emqx/emqx",{branch,"develop"}})
===> Failed to fetch and copy dep: {git,"https://github.com/emqx/emqx",
{branch,"develop"}}

Indeed there is no "develop" branch.

Update: users must initialize a git repo (e.g., git init) and initiate a commit to get a master branch created. The template code runs git to capture the branch name (in the folder generated by the rebar template). Since there is no branch until you commit (even after git init . there is no branch) the template fails to see "master" and falls back to "develop".

Side note: those new to emq (and Erlang development) would welcome some complete end-to-end steps to generating and deploying the plugin to emq. Thanks!
