[PATCH v2 2/2] Added test cases for git reset -

[Sudhanshu Shekhar <sudshekhar02@gmail.com>]

1) Confirm error message when git reset is used with no previous branch
2) Confirm git reset - works like git reset @{-1}
3) Confirm "-" is always treated as a commit unless the -- file option
is specified
