Describe the bug

I'm unsure if this is a bug or intended behavior, but it seems like on 0.10.0 it isn't possible to mix directed and undirected components in motifs?

To Reproduce

Single undirected works as expected and finds the motif undirected

graph.find("(a)-[b]-(c)").show(10, truncate=False)

But adding an additional component fails:

graph.find("(a)-[b]-(c); (c)-[d]->(e)").show(10, truncate=False)

Throws:

Py4JJavaError: An error occurred while calling o295.find.
: org.graphframes.InvalidParseException: Failed to parse bad motif string: '(a)-[b]-(c); (c)-[d]->(e)'.  Returned message: '->' expected but '-' found
	at org.graphframes.pattern.Pattern$.parse(patterns.scala:83)
	at org.graphframes.GraphFrame.findAugmentedPatterns(GraphFrame.scala:520)
	at org.graphframes.GraphFrame.find(GraphFrame.scala:515)

Expected behavior

It should be possible to mix directed and undirected motif components.
