"=" in cookie value causes ember-cookies to not see the cookie

[Josh Pyles]

When a valid cookie is set that contains = in the value it doesn't work. We discovered this issue because our session cookies always end in =.

document.cookie shows that the cookie is in fact present, meanwhile…
cookies.exists('session') returns false
cookies.read('session') returns undefined

It looks like the issue is where it splits the cookies by "=" and asserts that the length is === 2.

I'm not sure if there are other edge cases here, but one solution could be to use >= 2 instead. Alternatively you could manually assemble the key and value by doing something like unfilteredCookies.map(c => [c.slice(0, c.indexOf('=')), c.slice(c.indexOf('=') + 1)]).filter(...).
