  1. Move multiple-provide test into test_backtrace 

    Currently fails with:

    error[E0034]: multiple applicable items in scope
       --> tests/test_backtrace.rs:165:13
        |
    165 |             x: std::io::Error,
        |             ^ multiple `provide` found
        |
        = note: candidate #1 is defined in an impl of the trait `Provider` for the type `E`
        = note: candidate #2 is defined in an impl of the trait `std::error::Error` for the type `std::io::Error`
    help: disambiguate the associated function for candidate #1
