Fix travis build (#65)

* Changed `assert_eq!` tests to `assert!` to fix the build.
* Added semicolons to last line of functions to make pedantic clippy happy.
* Changed explicit impl of Default for timetoken.rs to be derived instead.
* Refactored assertion in subscription.rs to make clippy happy.
* Allowing unknown lints so that the build can pass. Older versions use `broken_intra_doc_links` and newer ones use `rustdoc::broken_intra_doc_links`, so the build fails on one or the other, so allowing unknown lints for now.
* Formatting to make the linter happy.
* Allowing unused async, because it's required for `ControlOutcome`, but Clippy insists it isn't.
* Resolving issues detected by Clippy: "expression borrows a reference...that is immediately dereferenced by the compiler"
* Bumping minimum version to Rust 1.49.0 due to:
- rust-lang/rust#55002
- rust-lang/rust#70921
* Added TODOs to remove linter allows for unknown, renamed, and removed lints when Rust 1.59.0 becomes minimum version.
* Added todo where the default UUID behavior is specified.
