* Update storage.js to match pageHelper.injectPageMetadata

At pageHelper.injectPageMetadata references editorKey and tags to build metadata, but this data seems not to be supplied to this function, since page object is only built from specified columns.

As a result, tags are always empty when exporting pages, and editor key appears as undefined.

It happens also with git storage, but may happen with another storage providers.

I run into this issue running Wiki.js 2.5.170 with the following Docker stack:
