[Craft 5] getElementProfile helper doesn't account for Matrix blocks with their own URI (there's no associated section handle)

[kylecotter]

Hi!

Craft 5 lets matrix blocks have their own URIs. With this type of setup the resulting matrix block element doesn't have a "section" associated with it, and therefore no handle for this line to grab.

This results in the hook 'seomateMeta' erroring.

To reproduce:

1. Create a section (and entry type for section) as normal
2. Create a matrix field that has uris (in our case the uri was {owner.uri}/{type|kebab})
3. Add matrix field to the entry type of the section
4. Create a new entry in the section, and a new block in the matrix field
5. Attempt to view the URL of the matrix block
6. Should get an error

Full stacktrace below:

Thanks a lot for reporting that! I just tagged SEOMate v. 3.0.0-beta.5, which should resolve the issue.

Additionally, this prodded me to finish implementing a feature that goes nicely with Craft 5's decoupled entry types and Matrix entrification: the ability to be more specific when mapping field profiles to elements via context prefixes such as "section:news" or "entryType:listPage". Read more about that here!

(...this new feature also means that SEOMate now gives you the ability to map field profiles to nested Matrix entry types).
