## Why
Discovered some rough edges in the API while making use of it more
widely within exec-server. It would be a lot more convenient for
existing users of `AbsolutePathBuf` if `PathUri` conversion methods
returned `std::io::Result`s.
## What
* `PathUri::to_native_path()` -> `PathUri::to_abs_path()`
* `PathUri::from_file_path()` -> `PathUri::from_abs_path()`
