Allow using all supported Moment inputs with TimeAgoPipe

[theodorejb]

Makes it possible to use TimeAgoPipe with string/number dates when the fullTemplateTypeCheck Angular compiler option is enabled. Fixes #204.

Also enables type checking when running tests. Previously a test could contain a type error, but all tests would be reported as passing since ts-jest only uses TypeScript as a file preprocessor (see kulshekhar/ts-jest#79).

This is a non-breaking change which can be included in a minor/patch release.

Thank you very much! See my comments regarding explicitly adding return types.

Also, interesting note regarding reporting type errors from jest - as far as I can remember, if you specify a value for tsConfig in ts-jest config, it does type check.

I tried this, but it didn't work. The tsConfig option is documented at https://kulshekhar.github.io/ts-jest/user/config/tsConfig. By default ts-jest uses the project's tsconfig.json file, and this is just a way to override that. It doesn't enable type checking when running tests.

There is a different enableTsDiagnostics ts-jest option which was documented in an old version of the readme. This actually does work - the test suite fails and I get a TypeScript compiler error when a test contains a type error. However, I wasn't sure about using this option since it isn't documented anymore, and the old documentation said it was an experimental feature that could be removed and will hurt performance.
