[User testing feedback] Tree navigation "up" arrow could be clearer

[charlesh88]

From Time Conductor and tree user testing sessions in October 2020, there was a bit of confusion on how the left "up" arrow works in the tree. Let's change the behavior a bit, in this way:

• Move "up" arrow down one level, so My Items would not have a nav up arrow. @jvigliotta
• Change "up" arrow glyph to use "nav-to-parent" icon. @charlesh88

Hey @charlesh88 I added the icon, but you'll need to tweak the css, I just kinda shoved it in there...

Testing

• navigate the tree and note that the "nav-to-parent" icon will navigate you back up to the item ABOVE that arrow
• make sure objectPath is correct by performing actions
• make sure to test with and without root showing
