Disasembler doesn't include object index for index 0 for dot notation.

Describe the bug

For dot notation (https://manual.gamemaker.io/monthly/en/GameMaker_Language/GML_Overview/Addressing_Variables_In_Other_Instances.htm), using the first game object results in no asset index in the disassembly.

For example, take if (obj_choicer_old.choiced == false). This incorrectly disassembles to:

push.v choiced
pushi.e 0
cmp.i.v EQ

This is because obj_choicer_old is the first Game Object in SURVEY_PROGRAM's Game Object list.
If it was instead the fourth game object, it would correctly disassemble to:

push.v 3.choiced
pushi.e 0
cmp.i.v EQ

I'm not sure if this affects pop opcodes too, but it probably does. I've got no proof of that though, so I'll leave this issue just for push.

Reproducing steps

• Open data.win of SURVEY_PROGRAM
• Go to gml_Object_obj_schoollobbycutscene_Step_0
• Go to Disassembly tab
• Search for choiced
• Will find push.v choiced instead of expected push.v 0.choiced

Setup Details

• UTMT Version: 7.0.0.0, also affects 6.x.x.x and 5.x.x.x, and probably all other versions too.
• OS: Windows 10
• Game: All games, anything where the first Game Object is used in dot notation. Can test using SURVEY_PROGRAM
