The test setup for `ProfileIntegTests` is flawed, where the full name of
a user can be a substring of other profile names (e.g., `SER` is a
substring of `User <random-string>-space1`) -- when that's passed into
suggest call with the `*` space, we get a match on all profiles, instead
of only the one profile expected in the test, since we are matching on
e.g. `SER*`. This PR restricts the setup to avoid the wildcard profile
for that particular test.
