Renames development configuration file to original name.

Seems to have been an accidental removal resultant from directions introduced in
944376c9. I've also modified the instructions to copy configs rather than move to prevent
in future.
Updates enddate to sometime far in future.

PHPUnit was failing because there was an expectation that creating a
talk would have a flash message of type=success, but did not take into
account enddate. I just updated the default value in the travis.dist config.
Whitespace fix.
Updates expected end-date in Behat feature for conference information.
Fixes typo that was causing undefined variable notices.
