Ref #1100: Java DSL Formatter - Format Java DSL when it's at start of route

[merkuspunto]

Fixes #1100

Motivation

A route beginning with the Java DSL does not get formatted, but the plug-in should format it.

Modifications

• Include method call expressions when finding the start of a route.

Results

Example of formatted code:

  from(direct("format"))
      .setBody(constant(Map.of("foo", "abc", "bar", 123)))
      .marshal(dataFormat);
  
  from(direct("format"))
      .setBody(constant(Map.of("foo", "abc", "bar", 123)))
      .marshal()
      .csv();
  
  from(direct("format"))
      .setBody(constant(Map.of("foo", "abc", "bar", 123)))
      .marshal(
          dataFormat()
              .csv()
              .delimiter(",")
          .end());

  routeTemplate("template")
      .templateParameter("v1")
      .from(kamelet("source"))
          .setProperty("version", constant("{{version}}"));
