Detect missing schemes for url resources

[jzbrooks]

If a string resource has a single variant that begins with common url schemes (http:, https:, mailto:, tel:, sms:, etc), every version of the string resource should begin with that prefix.

This has caused an issue where a string was updated in crowdin without a scheme for a specific locale which caused action view intents to not resolve, so the app would crash.

This might be a good starting point for this check since the translation detector also has to inspect every resource variant.
