Fix pytorch upsample parsing

[vloncar]

Description

The parser for PyTorch Upsampling layer ignores including the batch dimension in output shape, causing the failure of parsing subsequent layers. Fixes #1184.

Type of change

• Bug fix (non-breaking change that fixes an issue)

Tests

Extended test_upsampling_pytorch.py to have a layer afterwards.
