WIKI-793: Wrong behavior when creating page without title

Problem analysis:
* This is a side effect from WIKI-523. Autosaving is enabled before opening the confirmation pop-up

Fix description:
* Disable the autosaving before rendering the confirmation pop-up
WIKI-853: [Cloud] No content in Wiki syntax help (Edit source mode)

Analysis:
* Only the first tenant that accesses Wiki can have wiki syntax help panel.
* Once the Syntax Help panel displays, the help content is stored in DB. It no longer depends on "first tenant access" context.
* WikiServiceImpl uses an Iterator object to generate help page for wiki.
  This Iterator object will be empty from the second time (because the last element was already accessed)

Fix description
* Improve WikiServiceImpl to support multi-tenancy by itself
* Use List type instead of Iterator
