Latest BLT causes local:refresh to fail

[geerlingguy]

My system information:

• Operating system type: macOS
• Operating system version: 10.12.4
• BLT version: 8.x (latest HEAD)

When I run this command:

blt local:refresh

I get the following output:

...
blt > local:sync:db:

And I expected this to happen:

The database should be pulled down and the local:refresh should complete correctly.

Fix

It looks like the additional cache-rebuild in the local:sync:db target is not respecting the configured local drush alias.
