Daichi Hirono 0f6ab57eef Fix doc flag for device having multiple storages
Previously MtpDocumentsProvider#queryDocument returned
FLAG_DIR_SUPPORTS_CREATE for device having multiple storages.

This was wrong because if the device has multiple storages,
MtpDocumentsProvider places the storages under the device document, thus
users cannot create a document just under the device document.

Test: MtpDocumentsProviderTests
