test_vulkan: VVL error VUID-vkBeginCommandBuffer-commandBuffer-00049

> Validation Error: [ VUID-vkBeginCommandBuffer-commandBuffer-00049 ] | MessageID = 0x84029a9f
vkBeginCommandBuffer(): on active VkCommandBuffer 0x3b0a0df0 before it has completed. You must check command buffer fence before this call.
The Vulkan spec states: commandBuffer must not be in the recording or pending state (https://docs.vulkan.org/spec/latest/chapters/cmdbuffers.html#VUID-vkBeginCommandBuffer-commandBuffer-00049)

The issue identifies test_vulkan and the VUID-vkBeginCommandBuffer-commandBuffer-00049 validation error, but names no file or test entry point. Locate the test_vulkan coverage, reproduce the error, and trace command-buffer submission and fence handling; done means the test no longer triggers this VVL error while preserving conformance behavior.
