A recent update to contrib/completion/git-completion.bash causes bash to fail
auto complete custom commands that are wrapped with __git_func_wrap. Declaring
__git_cmd_idx=0 inside __git_func_wrap resolves the issue.

Fixes `bash: [: -lt: unary operator expected` error for tab completions
of wrapped `git` commands. For example, assume the convenience command
`gaa` defined in a shell script as
```bash
git aa "$@"
```
where `git aa` is an alias to `git add --all`. Then `gaa` is wrapped
for bash completion like
```bash
__git_complete gaa _git_add
```
For this example, the current bash completion fails at
`contrib/completion/git-completion.bash:1190` due to empty local
variable `c` as `__git_cmd_idx` is empty at the definition in
`contrib/completion/git-completion.bash:1179`. Defining
`__git_cmd_idx=0` earlier in `__git_func_wrap` attempts to solve this
problem.
