Alter an expression breakpoint deletes log message

[fr43nk]

Does this issue occur when all extensions are disabled?: No

• VS Code Version: 1.96.4
• OS Version: Windows 10

Steps to Reproduce:

1. Create a new Log point by right clicking and choose "Log point"
2. Enter some Text, and hit return
3. Again right click the log point and choose edit
4. choose "Expression" and enter an expression and hit return
5. Right click the log point, choose "Expression" and change the prior entered value and hit enter
6. the breakpoint symbol changes from diamond to circle and the log message is gone

Tested this with different debugger extension and the behavior is always the same.

Happy to look at a PR or discuss the approach. We just don't assign issues to public contributors

I think the issue was that updateBreakpoints replaced the entire breakpoint state, causing properties like logMessage to be lost when switching to an expression breakpoint. My code suggestion ensures properties are only overwritten if explicitly provided, by merging bpData with existing values. I also added a test to verify that updates correctly retain existing properties.
