Build repeat can't find a path despite only needing to move 1 block over (allowBreak false)

## Some information
Operating system: Windows 10
Java version: Version 8, Build build 1.8.0_251-b08
Minecraft version: 1.12.2
Baritone version: 1.2.14
Forge mods (if used): none

## Exception, error or logs

## How to reproduce
Add your steps to reproduce the issue/bug experienced here.
1. Create a schematic of a 1x2 block tower
2. Set allowBreak to false
3. set buildRepeat to 0,0,1
4. set buildRepeatCount to -1 (or any value greater than 1)
5. Create a 1x2 tunnel in the -z direction
6. Stand at the -z end of the tunnel and face towards -z
7. Run command "build <1x2.schematic file path> ~ ~ ~-1

Baritone will build the 2x1 tower at the end of the tunnel initially but won't walk backward to build it again, instead searching endlessly for other paths.

## Modified settings
allowBreak - false
buildRepeat - 0,0,1
chatControl - false
simplifyUnloadedYCoord - false

## Final checklist
- [x] I know how to properly use check boxes
- [x] I have included the version of Minecraft I'm running, baritone's version and forge mods (if used).
- [x] I have included logs, exceptions and / or steps to reproduce the issue.
- [x] I have not used any OwO's or UwU's in this issue.
