Revert "Bug 18619: If indexedDB disabled, use in-memory db for asyncStorage.js"

This reverts commit dcd2db035018a6e5466dcd27eb630dfd08995c71.

We don't need this patch anymore as we are relying on IndexedDB being disabled in Private Browsing Mode (PBM) and properly isolated in non-PBM. --- devtools/shared/async-storage.js | 38 ++++++-------------------------------- 1 file changed, 6 insertions(+), 32 deletions(-)
