mismatch between title variable and actual edm screen title for some motors

Expected Behavior

motor-expert-screen should finish executing and move the screen to the cursor irrespective of the type of motor

Current Behavior

For certain types of motors including but not limited to pulsepickers, aerotechs, and smaracts, the variabel title will not match the actual title of the screen opened, resulting in xdotool search --sync hanging forever, the screen never being aligned to the cursor, and motor-expert-screen never completing.

Possible Solution

I think the way title is set should be changed. Instead of having on if-elif-else block to set the title, and another to open the screen, we should only have one block where we set the title variable and another variable containing the command that will open the screen. At the end of the block, xdotool search for old windows, then execute the command. This will make it easier to make sure each different type of screen correctly sets the title variable.

Steps to Reproduce (for bugs)

1. Run motor-expert-screen with a pv for a pulsepicker, aerotech, or smaract motor (XPP:SB2:MMS:29, XCS:SND:T1:Y1, or XPP:MCS2:01:m1 respectively)
2. Observe that motor-expert-screen never finishes executing, it just stays in the foreground until you manually terminate it, and that the screen is never moved to your mouse by xdotool.

Context

I noticed it while working on #233. I also feel like I've noticed this before but never paid it much attention.

Your Environment

Start at the motor-expert-screen entry point and reproduce the issue with the pulsepicker, aerotech, or smaract PVs listed in the report. Trace where the screen title and opening command are selected, then verify that the command completes and xdotool moves the opened screen to the cursor for each motor type.
