frontend: increase hash length to 11 bytes

In changing the hash function and salt in https://golang.org/cl/84977
there is a (very small) chance that collisions may occur with newly
created snippets. If Bob created a snippet using the previous hash,
but Alice created a new snippet using the new method that happened to
have the same 10-byte string ID, then it would overwrite Bob’s snippet.

Increase the length by 1 to avoid this and to also clearly delineate
which are saved using the old method and which are using the new one.
