Fails to generate diagram with multiple internal Wikilinks

[kestoske]

What happened?

Everything works for a single link and links to external sources. Once I add multiple internal Wikilinks it keeps showing Generating PlantUML diagram. Example:

```plantuml-svg
Bob -> Alice : [[[test1]]]
Alice -> Wonderland: [[[test2]]]
Wonderland -> next: hello
next -> Last: hello
Last -> next: hello
next -> Wonderland : hello
Wonderland -> Alice : hello
Alice -> Bob: hello

From the error message it seems like that one of the linked files does not exist. Can you confirm that?

[kestoske]

On my local environment I was testing with existing files.

[kestoske]

As I understand the issue is here:

const file = this.plugin.app.metadataCache.getFirstLinkpathDest(split[0], path);

where split[0] = "test1]]]\r\nAlice -> Wonderland: [[[test2";

[joethei]

Yeah, thats what I found to, currently trying to reproduce another issue before shiping the fix.
