Save all generated images - incompatible with multi-step processes/templates

[evanjs]

When Save all generated images is enabled, templates that perform multiple steps appear to save only the first step once it is completed.

For example, consider the template templates/common/presets/facelift/best_quality_v4.txt:

[restore_faces unload="{get unload}" method=gfpgan image="{get body}"][faceswap "{get faces}" unload="{get unload_all}" visibility=0.75][restore_faces unload="{get unload}" method=gpen]

SD appears to save only after restore_faces is complete, and ignores the rest of the steps.
Even if the remaining steps are successful and the output appears in the WebUI, only the first intermediate output will be saved.

Manual saving appears to persist the output properly, even after the wrong (i.e. first intermediate) image is saved (via autosave)
