[BUG] `hook_install()` term creation failures during site installation from `--existing-config`

[adam-vessey]

What steps does it take to reproduce the issue?

• When does this issue occur?

Site installation using an --existing-config, with this module enabled.

• Which page does it occur on?

N/A

• What happens?

Don't recall the exact error, but it will attempt to create the term before the islandora_display taxonomy itself is configured, due to the site installation flow (was encountered previously with islandora_fits when dealing with the islandora-starter-site):

• enabling the module and running install hooks; before
• importing the existing configuration (which defines the taxonomy)

... looking back at https://github.com/roblib/islandora_fits/issues/12 , I'm not sure there's an explicit error, but just that the term will probably not carry the intended value for field_external_uri, but will instead be left blank.

• To whom does it occur (anonymous visitor, editor, administrator)?

Sys admin.

• What did you expect to happen?

The term to be able to be created without error.

Which version of Islandora are you using?

N/A

Any related open or closed issues to this bug report?

Same class of issue as https://github.com/roblib/islandora_fits/pull/14

I prefer (and seemed to have convinced others?) that we should take all the default config stuff including this term out, and put it in the Starter Site.
