Package main typings resolution is not consistent with normal resolution

[unional]

Don't know if this is intentional or is an unintended bug.

Currently if package.json/typings property is not specified, it defaults to read /index.d.ts, even if package.json/main is specified as things like dist/index.js.

In contrast, normal (relative) resolution would look for .d.ts next to the .js file.

Should tsc also tries to look up dist/index.d.ts in the above case?

This applies to 1.8 and 2.0.

i am sure there was an issue tracking this. but could not find it.

This issue seems to be resolved starting from Typescript 2.9.

I have found the respective logic in the code, but could not track when was exactly this implemented. Trying to build my project that does not have typings field, only main, I confirm, that the issue happens in typescript 2.8, but I do not see this in newer versions.

@unional can you re-check, please?

Yes, I think it is fixed. Tested in 3.2.2
