Fixes#14007.
We already know which list widget a `<th>`
tag is associated with when we set up the
event handler, so it's silly to read data
from the DOM to find that widget again
when the handler runs.
This commit eliminates a whole class of possible
errors and busy work.
Before this fix, we'd get a traceback if you looked
at invites in the settings (and if one of them was
a multi-user invite link). This commit fixes
that problem by adding a custom sort.
We also rename the "Email" column to "Invitee",
since it's often the case the invitee isn't an
actually an email, but it's instead a multi-use
link.
Note that the invites UI only works the first time you
enter settings. Many of the controls break the second
time you enter it. You can't sort by column header
or use the text filter.
I'll fix that in a subsequent commit.
