Possible issue with starting releases

[oubiwann]

When starting an LFE release with rebar3 lfe run-release start sometimes it doesn't actually start (checked by running rebar3 lfe run-release ping). However, almost always after running rebar3 release again, it will start, with a subsequent ping resulting in a pong.

Things to test:

• Generate a new project with rebar3 new lfe-release
• Generate a release for the project with rebar3 release
• Run the release script manually (./_build/..../app-name start)
  • do several series of starts and stops, pinging each time
  • make sure it always comes up
• Now run the rebar3 lfe run-release start command (without rebuilding the release) to check its behaviour
• Do a fresh rebuild of the release, and check again
• Create a new Erlang/OTP release (no LFE) using rebar3 new release
  • update the project's rebar.confg file and add the LFE plugin
  • use the LFE plugin command to run through the same steps above to see if the results are all the same
