[tizen] Fix issue with regular arrays in Bundle.

Bundle now stored byte streams as Uint8Arrays and converts regular arrays with
octet values to Uint8Arrays in Bundle::set() method.

toString() method now prints Uint8Arrays in the same way as regular arrays
using "[1,2,3]" format, instead of the "{0: 0, 1: 1, 2: 2}" format which is the
default behavior of toString() method on typed arrays.

[Verification] Modified tests passed.
