Repo was only used in two locations:
1. StripeButtons.set for `isCommons` - can be replaced by `descriptionUrl.includes('//commons.wikimedia.org/')`
2. EmbedFileFormatter.getSiteLink (unused)
Furthermore:
- Simplify StripeButtons (we only have one button)
- Unwrap info objects consisting of `ImageModel` and `Repo`
- Remove unused EmbedFileFormatter.getSiteLink
- Inline EmbedFileFormatter.getCaption and EmbedFileFormatter.getLinkUrl
- Fix JSDoc type `ImageModel`
Reduces mmv bundle size from 28012 to 27246.

Use the eslint rule
"no-var": "error"
in resources/.eslintrc.json and in .eslintrc.json
to require the use of `const` and `let` instead of `var`.

* Removed deprecated testCount, which is no longer supported in this way.
It's only useful when wanting to explicitly expect 0 assertions (normally
considered an error).
* Replaced use of testCount = 0, with assert.expect( 0 ).
