Fix names of options to match the exported types

[markjm]

The names of the new export options do not match the names present in the options schema. Note how different places have an "s" after exports while some don't. This change simply fixes all cases where the options used in webpack didn't match the outward display names.

reexportExportsPresence?: false | "error" | "warn" | "auto";

@sokra this could have been caught if options schema disallowed additionalProperties on JavascriptParserOptions. Wondering if that is set as such for a reason, I guess if not, it is technically breaking change to fix that

@markjm The most important CI builds failed. This way your PR can't be merged.

Please take a look at the CI results from azure (0 errors / 5 warnings) and appveyor (failure) and fix these issues.
