Rust-crypto: fix
bootstrapCrossSigning
on second call (#3912)
* Rust-crypto: fix `bootstrapCrossSigning` on second call Currently, `bootstrapCrossSigning` raises an exception if it is called a second time before secret storage is set up. It is easily fixed by checking that 4S is set up before trying to export to 4S. Also a few logging fixes while we're in the area. * Factor out an `AccountDataAccumulator` * Another test for bootstrapCrossSigning
