fix db store files to use symbols instead of strings
again fix fixtures to use symbols intead of strings

Had fixed camelCase to snake_case but forgot about the
front part of the symbol for the fixtures.
undo symbol change for json

json returns a string not symbols. fix issue with what we are
testing.
fix symbols and regexes so tests pass

Regexes needed to be rewritten :navigation_start should become
:name => "Navigation". Also fix remaining strings that were not set
to symbols. In tests I was overzealous with switching strings to
symbols and had to undo some.
Merge branch 'get-tests-passing' into clean-up-class-structure-that-uses-strings-as-keys-and-crazy-non-objects
