[TASK] Improve type checking error

[Serial-ATA]

Overview

When doing a job call, type checking is performed, and the cause of errors is known:

tangle/primitives/src/services/jobs.rs

Lines 135 to 157 in 7ee0572

	pub fn type_checker<C: Constraints, AccountId: Encode + Clone>(
	params: &[FieldType],
	args: &[Field<C, AccountId>],
	) -> Result<(), TypeCheckError> {
	if params.len() != args.len() {
	return Err(TypeCheckError::NotEnoughArguments {
	expected: params.len() as u8,
	actual: args.len() as u8,
	});
	}
	for i in 0..args.len() {
	let arg = &args[i];
	let expected = &params[i];
	if arg != expected {
	return Err(TypeCheckError::ArgumentTypeMismatch {
	index: i as u8,
	expected: expected.clone(),
	actual: arg.clone().into(),
	});
	}
	}
	Ok(())
	}

However, the error is then immediately converted to one with no information:

tangle/pallets/services/src/lib.rs

Line 1360 in 7ee0572

job_call.type_check(job_def).map_err(Error::<T>::TypeCheck)?;

We should retain the information from the original error, otherwise it isn't clear what's gone wrong.
