Activity Diagram: Code format issue when double parenthesis in if

[jonathanhuet]

When inside the condition of the if clause there is a pair of parenthesis, formatter adds a carry return and breaks the ssyntaxis of the diagram.

Example:

This following plantUML code is manually correctly formatted

@startuml
title : Formatter double parenthesis issue
start
if (exists(error)) then (yes)
    :throw (Exception(null));
endif
stop
@enduml

But when autoformatting the result is the following

@startuml
title : Formatter double parenthesis issue
start
if (exists(error)
    ) then (yes)
    :throw (Exception(null));
endif
stop
@enduml

That causes the following issue in the diagram renderer:

Note: The double parenthesis inside the throw is formatted perfectly
