- fix: template functionInitialResidual() a stronger test for no resi…

…dual equations

  it could produce an empty array initialization when there is only an "initial algorithm" section 
  and no "initial equation" in the model (so that residualEquations is not empty {}, but it has no SES_RESIDUAL(__))
- fix: a copy/paste typo error in template literalExpConst() to properly count lengths of the unescaped strings
