[2/n] Ignore current params in desktop launch params

Current params can be restored/ presisted from previous states and thus
might not accurately represent the destination state of the task /
applicaton (i.e just because current params have freeform mode doen't
necessarily mean the task wants to enter freeform). Due to this
uncertainty as well as the current params not acutally being necessary
to resolve desktop mode specific launch param, we will ignore them
during the calculation.
