Bump version

Since it's a minor release we align all crates versions (even if there were no changes).

Tests (compile tests) are failing: the same failure I sometimes get locally - fixed with a cargo clean.

error[E0464]: multiple matching crates for `jsonrpc_core`

Odd that it should happen on CI. I've just done a clean build locally on td-ver and it passes.
