worker-api fails to send TOP with long note

[brenzi]

The worker will accept notes up to 256 bytes

However, worker-api fails to encrypt the TOP if the note is 169 bytes, i.e. 123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678
