Fixed tests on master

[svyatonik]

Guess this was caused by merging #1758 after #1730:

---- wasm_executor::tests::sr25519_verify_should_work stdout ----
thread 'wasm_executor::tests::sr25519_verify_should_work' panicked at 'called `Result::unwrap()` on an `Err` value: Error(Wasmi(Function("Module doesn\'t have export test_sr25519_verify")), State { next_error: None, backtrace: InternalBacktrace { backtrace: Some(stack backtrace:
   0: error_chain::backtrace::imp::InternalBacktrace::new::h8fe770682d4a0439 (0x5587efdb6bf8)
   1: <error_chain::State as core::default::Default>::default::hfff3861ac64abe1a (0x5587efdb6985)

./scripts/build.sh has helped

It is interesting that I've noticed that when merging master into #1779 && now I could see that PR has compiled successfully. Not sure why it passes CI :-/

Seems like some local issue
