Integers in invoke should allow greater precision

[roadbuilder]

When calling an invoke with an (integer), the precision seems to be limited to 19 digits. So if I have an 18 decimal NEP17 token and I want to invoke an amount greater than 9 of the tokens (which is 9,000,000,000,000,000,000), such as 100 SFI

it gets an error saying:

if I try and send less such as 9 tokens, it will go through without a problem.

also sending using the Neoline extension in javascript works fine and allows the full precision.
