[pbs-devel] [PATCH backup 03/13] backup_manager: use Vec::first instead of get(0)

[Maximiliano Sandoval]

Fixes the get_first clippy lint:

```
warning: accessing first element with `matching_stores.get(0)`
   --> src/bin/proxmox_backup_manager/datastore.rs:284:26
    |
284 |     if let Some(store) = matching_stores.get(0) {
    |                          ^^^^^^^^^^^^^^^^^^^^^^ help: try: `matching_stores.first()`
    |
    = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#get_first
    = note: `#[warn(clippy::get_first)]` on by default
```
