This closes#10146.
Because of cibernox/ember-power-select#1203, which documents
the current impossibility of attaching test selectors to a
PowerSelect invocation, this uses test selectors on parent
containers instead, occasionally adding wrappers when needed.
I chose to leave the existing test selectors in the hopes that
we can return to using them eventually, but I could easily
remove them if it seems like extra noise now.
Presumably for the same reason, @class no longer works, so
this adjusts the scoping of global search CSS to preserve the style
of the search control.
I also included an update to the latest version of
ember-test-selectors, since we were far behind and I tried
that before finding the aforelinked issue.
Finally, this replaces ember-cli-uglify with ember-cli-terser to address
production build failures as described at ember-cli/ember-cli#9290.
This is mostly a direct application of the ember-angle-brackets-codemod.
I manually restored newlines in multi-line component invocations, usually
preserving file line length except for now-non-positional link-to @route.
I needed to rename task to taskState in some cases to avoid Ember
Concurrency naming conflicts.
This is mostly deprecation fixes and blueprint changes. There
are some dependency updates too; the changes to Ember
Basic Dropdown necessitated changing it to angle bracket
component invocation. The conversion of the rest of the
templates will happen separately.
The UI will no longer try to redirect to the appropriate namespace or
region if one is found in localStorage. Instead, it will assume that
the lack of query param means the default namespaces or region is
desired.
