Missing column header in CSV-Export of AnalysisCallTree

[ChristophTF]

Describe the issue
When exporting the analysis call tree in CSV files, the report file call_tree_virtual_methods*.csv_ misses the last column header "Flags".

Steps to reproduce the issue

1. native-image HelloWorld -H:+PrintAnalysisCallTree -H:PrintAnalysisCallTreeType=CSV
2. Look at "call_tree_virtual_methods_helloworld_[date]_[time].csv"

Excerpt from the file "call_tree_virtual_methods_helloworld_[date]_[time].csv":

Id,Name,Type,Parameters,Return,Display
13155,parse,sun.nio.cs.Surrogate$Parser,char java.nio.CharBuffer,int,s.n.c.SP.parse,p

The first line is missing ",Flags"

Code location
The issue is caused by CallTreePrinter.printVirtualNodes(...)

graal/substratevm/src/com.oracle.graal.pointsto/src/com/oracle/graal/pointsto/reports/CallTreePrinter.java

Line 464 in 4e63029

writer.println(convertToCSV("Id", "Name", "Type", "Parameters", "Return", "Display"));

which in contrast to CallTreePrinter.printMethodNodes(...)

graal/substratevm/src/com.oracle.graal.pointsto/src/com/oracle/graal/pointsto/reports/CallTreePrinter.java

Line 403 in 4e63029

writer.println(convertToCSV("Id", "Name", "Type", "Parameters", "Return", "Display", "Flags"));

does not have the Flags header column.
