[*] Fixed a problem with the fact that if you do not specify a wallet for the transaction, there will be an error. Now the wallet needs to be specified for transactions in not the native ticker, but certificates in the native one.

[*] Added a check that the datum hash is not NULL at the input of the s_com_mempool_check_datum_in_chain function

[*] Fixed a crash when executing the th_history -all command if the network is not specified. Also added command description to help.
