func build/run doesn't pick up code changes

func verison
v0.46.3

```
$ func create -l python sentiment-analysis-app
$ cd sentiment-analysis-app
$ func build -v
...
$ func run -v
...
# stop the func run
$ # change some code
$ func run -v
...
$ func invoke ... 
```

When changing the code I updated a bunch of log lines but the changes weren't showing up in the second invocation
