Resolves: https://bitrise.atlassian.net/browse/STEP-1715

Changes

• Install certificate for locally found provisioning profiles. An alternative could have been to check weather certificate is already installed in the Keychain, always installing is the easier solution.
  There was no check earlier that the selected certificate (or any certificate in the profile) was installed. This could have led to an error:
  • A Step with automatic code signing installs Profile1, this induces Cert1 and Cert2. Cert1 is selected (to be set as signing certificate in the project). Profile1 is added, Cert1 is added to the Keychain. (Cert2 is not added.)
  • xcodebuild archive runs successfully
  • Another Step with automatic code signing is run. This time the previously added Profile1 is found. However now Cert2 is selected (randomly), it is not installed due to missing check.
  • xcodebuild archive fails with error:

❌  error: No certificate for team 'AAABBBCCC' matching 'dcdcdc' found: Select a different signing certificate for CODE_SIGN_IDENTITY, a team that matches your selected certificate, or switch to automatic provisioning. (...)
