fix(session): dap terminal buffer name

[cladera]

Set terminal dap buffer name with protected call. If setting buffer name fails, use a placeholder.

Fixes #722

Can you explain what kind of names lead to the error? The reproduction steps in #722 don't reproduce the issue because it's depending on the class/test name

[cladera]

Hi @mfussenegger! Sorry for not responding you back sooner. I could reproduce the error with the following class and method name:

com.cgc.nvimdap.HelloControllerTests#shouldReturnHelloWorld

[mfussenegger]

That's odd, calling lua vim.api.nvim_buf_set_name(0, '[dap-terminal] com.cgc.nvimdap.HelloControllerTests#shouldReturnHelloWorld') works fine for me. Could you show the error message you got?
