Use true-case-path to fix re-entrancy issue on Windows and Webpack

[amilajack]

This issue is a fix for #818. This issue is similar to sass/node-sass#2149, which

When using node-sass through multiple entry points (as can happen when using webpack) on Windows, the casing of the drive letter in the path can be inconsistent. Since Node is case-sensitive to a fault, this results in Node attempting to create a second instance of the native binding, which results in a Module did not self-register error.

The fix is to use true-case-path to normalize the binding path, to prevent unintended duplicate bindings from occurring.

I appreciate you doing this but

• you didn't sign the OCA before submitting

• I really don't want 3rd party code included for legal & security reasons.

I have followed the directions here for the OCA. I submitted mine a few minutes ago. Does it take time to process?

Edit: Fixed it

I've no plans to merge this because it injects 3rd party code into the install - a security issue. I'd be happy to merge a PR that directly patched node-oracledb code.
