Wrap the name retrieval of pEnv.ref with try-catch

[GUIEEN]

        env.name = pEnv.ref.name
            .cast<Utf8>()
            .toDartString(); // This always fails one time in this loop

I can't inspect the function code(getEnvironmentList) called by ffi, only thing I could check is symbols are registered from ./libailia.dylib binary file.

not sure why ref.name is failing on conversion to dart's string type.
