CliProfileManager.deleteProfiles not handling all of secure values with one call

[JillieBeanSim]

Zowe Explorer calls this CliProfileManager().delete() for v1 profiles. If these profiles are created using a v2 release the call will fail and if numerous attempts are made on the same profile it will succeed on the 3rd try. Each attempt returning a different error, attempt 1 returns Unable to delete the secure field "user"... the 2nd attempt return error Unable to delete the secure field "password"... and the 3rd attempt will succeed.
