Do NOT call TeamsInfo.getMember for the bot

[EricDahlvang]

Fixes: #2233

[EricDahlvang]

Investigating ... these tests are passing locally:

But failing in the build pipeline:

 1) TeamsInfo
       getMember()
         should work without a Team:

      AssertionError [ERR_ASSERTION]: The expression evaluated to a falsy value:

  assert(fetchExpectation.isDone())

      + expected - actual

      -false
      +true
      
      at Context.<anonymous> (libraries/botbuilder/tests/teamsInfo.test.js:406:13)


  2) TeamsInfo
       getMember()
         should work with a Team:

      AssertionError [ERR_ASSERTION]: The expression evaluated to a falsy value:

  assert(fetchExpectation.isDone())

      + expected - actual

      -false
      +true
