no-large-snapshots should not care about file types

[G-Rath]

Currently, no-large-snapshots checks if the file being linted ends w/ the .js file extension, preventing it from linting other files, such as .tsx, .ts, & .jsx.

This file check should be removed.

} else if (context.getFilename().endsWith('.js')) {

Potentially a breaking change, but I'd call it a bugfix...

It was added in #186, @JohanBrorson thoughts on just removing the check? We should just return from the .snap if

[G-Rath]

I can confirm that it does mean .ts files won't be linted by this rule.

Aside from that, I wouldn't really call it "breaking" per say, for the same reason prefer-to-spyon shouldn't bother trying to figure out if it's in a test file: eslint-plugin-jest is only meant for jest tests suites.

@G-Rath, @SimenB, @JohanBrorson We have our tests written in TypeScript, so we need it to be fixed. I created the following PR: #581
It is not passing due to some reason though, could you take a look?
