Doesn't evaluate each set of token_or conditions independently

Problem/Motivation

Similar to the related issue: #3307176: Token is not cleared if none of the tokens produce a replacement
When using "Or" conditions at the beginning of a token, it doesn't evaluate the second set of tokens in the string. The use case would be generating the path auto pattern using different field conditions.

Steps to reproduce

Create 2 text fields on a node
set up the path auto pattern to be something like [node:field_foo|node:field_bar]/[node:title]
Create a node of that type, but leave the two fields empty.
Observe the issue
Edit the node, and populate either of the fields
Re-save and observe the pattern was applied correctly.

Proposed resolution

Treat each token set independently.
