WIKI-863 Spelling mistake in Children macro
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
WIKI-846: [Advanced Search] Wiki Page's content inside Search Result

Problem analysis:
* WIKI-748 changes the indexing configuration for Wiki Page's content.
  The indexation and then searching is done inside Wiki Page's content instead of the whole Wiki Page node.
  When the keyword is found in Wiki Page's content, the result is therefore a wiki:attachment.

Fix description:
* Handle correctly the excerpt when the result is a Wiki Page's content.
