shared-state creates an unnecesary file when doing get

[nicopace]

Expected behaviour: for the get to be read-only
Actual behaviour: I called shared-state with a typo (one mispelled letter), and it created a file in /tmp/shared-state/data with that mispelled typo.

# shared-state get Dnsmasq-hosts.json
[]
# ls /tmp/shared-state/data/
... Dnsmasq-hosts.json ...

Maybe it gets created here, I did not check in order to confirm:

lime-packages/packages/shared-state/files/usr/lib/lua/shared-state.lua

Lines 48 to 49 in dcb099e

	self.storageFD = nixio.open(
	self.dataFile, nixio.open_flags("rdwr", "creat") )

Due to the lack of documentation (#492) I have no idea if this is a bug or not.
@G10h4ck or @spiccinini could know.
For now, as it is not clearly a bug and its impact seems minimal, I am going to close this. Feel free to re-open.
