get_type_id no longer exists on Rust 1.33.0

[asomers]

get_type_id has been stabilized and renamed to type_id in Rust 1.33.0. As a result, Mocktopus no longer builds with a nightly compiler as of 2019-01-25. rust-lang/rust#27745

Hello, old issue but I ran into the inverse of this issue while using an older nightly (cargo 1.33.0-nightly (2b4a5f1f0 2019-01-12)) for RLS reasons. So, for future Googlers, this error:

foo@bar ~/w/acw-api.rs> cargo test -- --nocapture --ignored
   Compiling mocktopus v0.7.0
error[E0599]: no method named `type_id` found for type `[closure@/Users/foo/.cargo/registry/src/github.com-1ecc6299db9ec823/mocktopus-0.7.0/src/mocking.rs:128:9: 128:15]` in the current scope

    |                ^^^^^^^

    = note: (||()) is a function, perhaps you wish to call it

error: aborting due to previous error

For more information about this error, try `rustc --explain E0599`.

Was fixed with the following:

rustup install nightly-2019-01-26
rustup default nightly-2019-01-26
rustup component add rls-preview rust-analysis rust-src --toolchain nightly-2019-01-26

Note that I used the 26th, not the 25th, as RLS didn't seem to be available for the 25th.
