Empty variable: multiple error messages

[mgrunko]

If there is an empty variable, IntelliBot throws multiple exceptions (about 100), so that IntelliJ stops monitoring.

To reproduce it, type a variable and simple do not write its value (screenshot hier)

I got the following two errors:

1. IntelliJ: com.intellij.diagnostic.MessagePool$TooManyErrorsException: Too many IDE fatal errors. Monitoring stopped.
2. IntelliBot:

PsiElement(VARIABLE_DEFINITION) java.lang.AssertionError: PsiElement(VARIABLE_DEFINITION) at com.intellij.psi.impl.source.text.DiffLog$InsertEntry.(DiffLog.java:175) at com.intellij.psi.impl.source.text.DiffLog$InsertEntry.(DiffLog.java:169) at com.intellij.psi.impl.source.text.DiffLog.nodeInserted(DiffLog.java:88) at com.intellij.psi.impl.source.text.DiffLog.nodeInserted(DiffLog.java:41) at com.intellij.lang.impl.PsiBuilderImpl$ConvertFromTokensToASTBuilder.nodeInserted(PsiBuilderImpl.java:1197)
