Missing 'wp/v2' in path in Location Response header

[johanmynhardt]

When submitting a Post Meta Create request, the response contains
a Location header with 'wp/v2' missing from the path.

Currently either $this->parent_base returns the wrong (empty) base,
or wp/v2/ is missing from the base when setting the Location header
for a Post Meta Create response.

Actual Location header

c.a.w.w.v.Client.debugRequest() - Request Entity:\
    <POST http://johan-wp/wp-json/wp/v2/posts/3766/meta,\
    {key=Gomxw, value=bLfaU},\
    {Authorization=[Basic am9oYW4ubXluaGFyZHQ6d29yZHByZXNzIQ==]}>
c.a.w.w.v.Client.debugHeaders() - Response Headers:
...
c.a.w.w.v.Client.lambda$debugHeaders$8() - \
    Location -> [http://johan-wp/wp-json/posts/3766/meta/11965]
...

Expected Location header

c.a.w.w.v.Client.debugRequest() - Request Entity:\
    <POST http://johan-wp/wp-json/wp/v2/posts/3766/meta,\
    {key=Gomxw, value=bLfaU},\
    {Authorization=[Basic am9oYW4ubXluaGFyZHQ6d29yZHByZXNzIQ==]}>
c.a.w.w.v.Client.debugHeaders() - Response Headers:
...
c.a.w.w.v.Client.lambda$debugHeaders$8() - \
    Location -> [http://johan-wp/wp-json/wp/v2/posts/3766/meta/11965]
...
