See #1277, but for LoadDataChange, CreateProcedureChange or CreateViewChange.

Steps To Reproduce

List the steps to reproduce the behavior.

• create a changelog file with these change sets

  <databaseChangeLog xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
    			     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    			     xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog
                        http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.10.xsd"
    			     logicalFilePath="a-logical-file-path"
  >
      <changeSet id="1" author="author">
    	  <loadData file="data/some_data.csv" tableName="a_tabe"
    			   relativeToChangelogFile="true"></loadData>
      </changeSet>
  
      <changeSet id="2" author="author">
    	  <createProcedure path="sql/proc.sql"
    					   relativeToChangelogFile="true"></createProcedure>
      </changeSet>
  
      <changeSet id="3" author="author">
    	  <createView path="sql/view.sql" viewName="a_view"
    				  relativeToChangelogFile="true"></createView>
      </changeSet>
  
  </databaseChangeLog>
  

• Create these files (may be empty)
  • data/some_data.csv
  • sql/proc.sql
  • sql/view.sql
• Run liquibase update against the db

liquibase --driver=com.microsoft.sqlserver.jdbc.SQLServerDriver --url="jdbc:sqlserver://localhost:1433;database=the_database" --changeLogFile=changelog.xml  --username=the_username --password=thepassword --logLevel=debug update

• See it fail
• Comment the changeset and repeat (fails for all three)

Actual Behavior

Liquibase throws an exception complaining about missing file (a different one for each changeset):

liquibase.exception.LiquibaseException: liquibase.exception.UnexpectedLiquibaseException: File 'data/some_data.csv' not found

Expected/Desired Behavior

Liquibase does not complain about missing files and works flawlessly.

Additional Context

Same bug has already been fixed in #1798 for a diffenent change. The changes above have been overlooked.

I had to fix an existing testcase which used a changeset not included in an changelog.
