Fix URI generated for canonical tag

[mxgnr]

Hi there,

First of all, thanks for making this useful plugin which i'm currently using for a project.

My main concern was about the canonical tag generated by the plugin, since i figured out that it is not working properly with my WP domain configuration :

• Main domain of the WP instance :
  https://www.example.com/some-subfolder/ ( this is actually the value returned by home_url() )
• Other domain added via the multi-domain plugin settings :
  https://subdomain.example.com/some-subfolder/

The other domain is working properly with this plugin, but when i browse to a category for example and i check the canonical URL generated by the plugin, it will display :

• <link rel="canonical" href="https://www.example.com/category/my-category/" />
• instead of <link rel="canonical" href="https://www.example.com/some-subfolder/category/my-category/" />.

I've tried some changes by setting the URI according to home_url() WP configuration instead of making it from scratch as it is currently, which seems to be working but might need some additional tests. (See #75)

Feel free to check if you can confirm this issue.

Hey @maxgranier, thanks for your contribution! I'll try to test it over this coming weekend and I let you know if there is any issue. Otherwise, I'll go ahead and merge your PR.
