Config wizard errors when remote repository is empty

[Altreus]

Actual behavior

During configuration wizard, ability to pull master appears to be a heuristic for whether the remote git repository is working. It is necessary to create a dummy file in the repo before the wizard will complete.

Expected behavior

Wizard should expect remote repository to be new and thus not contain any refs.

Steps to reproduce the behavior

• Begin brand-new wiki.js installation
• All prerequisites met
• Launch and connect to configuration wizard
• Create blank repository on github
• Provide credentials for this repository during configuration wizard

Wizard breaks at this point with error about remote ref master.

• Create any file at all on the github repo and commit it (the links on the github page suffice)

Wizard will now continue.

v1 requires the remote to be initialized first.

Upcoming v2 handles uninitialized repos correctly.
