Use fully qualified module name when running cargo-mode-test-current-buffer

[sunng87]

In my situation, I have a test module in my module

// abc.rs

#[cfg(test)]
mod tests {

  ...
}

If I call cargo-mde-test-current-buffer with cursor inside tests module, the generated command is cargo test tests, instead of cargo test abc or cargo test abc::tests

@sunng87 hello. sorry for a late reply. I think it shouldn't be hard to implement this feature. since we already have cargo-mode--current-mod function which returns the current module

I think the problem is cargo-mode--current-mode function always returns tests for these test module, and returns nil when the cursor is in a normal code module.
