Last error message is displayed after a CTRL-C when the openroad command is piped

Describe the bug

Last error message is displayed after a CTRL-C when the openroad command is piped.
I tested 3 commands (an false one foobar, read_lef and sv_elav) which print respectively 1, 2 & 3 error lines).

Here are the ouput without piping:

Error: foobar.tcl, 1 invalid command name "foobar"
openroad> 

[ERROR STA-0565] read_lef requires one positional argument.
Error: read_lef.tcl, 1 STA-0565
openroad> 

error: no input files
[ERROR SYN-0001] Elaboration failed.
Error: sv_elab.tcl, 1 SYN-0001
openroad> 

Here are the ouput with piping:

openroad> Error: foobar.tcl, 1 invalid command name "foobar"


[ERROR STA-0565] read_lef requires one positional argument.
openroad> Error: read_lef.tcl, 1 STA-0565


error: no input files
[ERROR SYN-0001] Elaboration failed.
openroad> Error: sv_elab.tcl, 1 SYN-0001

Note that in case of a wrong command (ex foobar), we don't even see there is an error. It took me some time before figuring out there was an error hence the report to help debugging.
