Fix empty WHERE clause in resourcelist TV input (2.x)

[colorwebdesigner]

What does it do?

Fixes SQL syntax generation in resourcelist TV render when:

• where parameter contains complex JSON conditions (e.g., [{"published":"1"}, {"hidemenu":"0"}])
• Used in MIGx configurations with direct JSON input
• Maintains compatibility with standard MODX TV settings

Why is it needed?

• Prevents SQL errors when resourcelist TV uses array-style where conditions
• Critical for MIGx configurations where TV parameters are defined via JSON
• Original bug: Broken SQL query when where contains nested objects

How to test

The error was observed in MODx version 2.8.8-pl
1. Configuration for resourcelist TV in MIGx

{"allowBlank":1,"showNone":1,"parents":"1,2,3","includeParent":1,"where":[{"published":"1"},{"hidemenu":"0"}],"limit":"0"}

Verify:

• Resources load without SQL errors in MIGxDB interface (?a=index&namespace=migx&configs=...)
• Filters by published=1 and hidemenu=0 are applied correctly

2. Standard MODX TV:

• Create TV with resourcelist input type
• Set "Where Conditions" to:

  [{"published":"1"}, {"hidemenu":"0"}]

Check resource selection in manager.
