Fatal error due to specific supplied data

[nickevansuk]

The following data crashes the entire app on Heroku

{
  "@type": "ImageObject",
  "url": "https://reachstorageaccount.blob.core.windows.net/images/9142d700-adb7-4f7b-af10-fef045ff11f4/783cbdc4-c0c0-449b-8ce0-1e147337a628/The Regal - Bball Court.jpg"
}

Possibly related to the "an aside" mention in #377 - as currently every string is parsed as a URI Template.

Interestingly validation of this data gets exponentially slower the longer it gets / more domains that are added:

{
  "@type": "ImageObject",
  "url": "https://domain1.domain2.domain3.domain4.net/ "
}
