Continue fixing even if fix leads to an error

[Pyr0de]

Running cargo-fixit on typos with the lints from https://pastebin.com/VMJCT2M2, it does not exit successfully while cargo fix successfully applies some fixes.

The command I used to run it

RUSTFLAGS="`cat ../clippy-lints.txt`" cargo fixit --clippy --workspace --all-targets

The first pass seems to apply some fixes but cargo check fails in the second pass.

This is being caused because of the lints clippy::std-instead-of-core and single-use-lifetimes. This behaviour is also seen in cargo fix.

I initially missed this because cargo fix just reverts the change and continues even if a fix leads to an error. We should probably change fixit to behave the same.
