Update default TLS protocol version in the config file

Mhm, this most likely should also include a change in the dependencies.tsv to pull in a newer minimal version of phoenix. I suggest that you also remove the mentioning of SSLv3 making TLSv1 the minimal version. Though the first Go version where it actually can be recommended to run the server with its native TLS listener is Go 1.8.

@longsleep Should I completely remove support for SSLv3 from phoenix or only the references in the Spreed WebRTC config file?

Just remove the reference in the config file and bump dependencies.tsv to the latest release of phoenix. Also make sure to check that minimal Go version for phoenix does conflict with that used here.

Updated. dependencies.tsv already points to the latest phoenix release commit (strukturag/phoenix@8c65e16).
