fix(indicate typos): Replace tabs with _ when indicate typos is replace or both (@Leonabcd123)

[Leonabcd123]

Description

When indicate typos is set to replace or to both, make sure to have tabs replaced with _.

Current behavior is that the literal tab character replaces the char, making it disappear.

Also, I'm pretty sure that checking whether inputChars[i] === " " is useless, as inputChars will never contain a space (inputChars is just input split into characters, input is TestInput.input.current, and TestInput.input.current will be empty after a space).

There's this one time where input is inputOverride, and that should be just TestInput.input.current + options.data.
