Update git submodules

* Update docs/submodules/portal.git from branch 'master'
  to 8b67487fa29e61ad15ac961231ebb3b6621d39dc
  - Merge "Sonar: Reduce cyclomatic complexity"
  - Sonar: Reduce cyclomatic complexity

    Reduce the number of conditional operators for equals(). Improve
    testEquals() to better cover this method.

    This patch also:

    * immediately returns expression instead of assigning it to the
      temporary variable "str",
    * adds the "@Override" annotation above equals() method signature.
