INTEG-328: [integ-ecms] Wrong File/Content activities of renamed spaces

Problem analysis:
* When renaming a space, its (pretty) name changes but its group ID and drive don't.
  SpaceService#getSpaceByPrettyName must be therefore replaced by SpaceService#getSpaceByGroupId.

Fix description:
* Implement getSpaceFromNode method to retrieve the space from the JCR node for a content/file added into the space's drive.
INTEG-328: Fix the method name in ContentUIActivity.gtmpl
INTEG-328: Revert changes in template files.

Fix description:
* The space name is updated thanks to SOC-4332.
INTEG-328: Delete redundant method
